Using Surround in Logic Pro
Logic Pro offers extensive surround processing and mixing functions for all major surround
formats.
Surround features are available when Show Advanced Tools is selected in the Advanced
preferences pane.
All audio signals can be positionally mixed, allowing you to place them anywhere in the
surround field. See Logic Pro Surround Panner overview and Surround master channel strip
in Logic Pro.
You can insert surround plug-ins into audio and instrument channel strips, which can be
routed to surround auxes or outputs. A number of surround and multichannel effects and
instruments are included. See Use surround effects in Logic Pro and Multichannel effects.
Incoming multichannel audio is recorded as interleaved multichannel files when creating a
surround project. Imported split multichannel files are converted automatically.
You can also upmix or downmix non-matching signals (mono to multi-mono, or stereo to
surround, for example), allowing you to use any audio material in your surround projects.
In most cases, upmixing or downmixing is automatic, but it can be performed manually,
if required. For more information, see the Down Mixer controls chapter in the Logic Pro
Effects manual.
You can bounce multichannel projects as split and interleaved surround files. See Bounce
surround audio files in Logic Pro.
Logic Pro does not encode or decode surround files. You can use the Compressor app,
available in the Mac App Store, to encode surround files.
To work with surround, you need an audio interface that has the number of output channels
required by the chosen surround format; for example, six outputs if the 5.1 surround format
is used. You will also need the same number of speakers (and appropriate amplification) to
hear the channels when mixing. See Logic Pro surround formats overview.
